ADJUSTABLE SPRAY-NOZZLE.

Specification of Letters Patent.

Application filed June 17, 1912.

Patented Nov. 1-8, 1913. serial No. 704,003.

To all fic/1.0m z't may conce-rn Be it known that I, EARLD H. LAMIELL, acitizen of the United States, residing at Canton, in thc county of Starkand State of Ohio, have invented a new and useful AdjustableSpray-Nozzle, of which the. following is a specification.

My invention relates to improvements in spray nozzles, and whileapplicable to many uses is peculiarly adapted for use in sprayinginsecticides and fungicides.

The objects of the invention are to provide a simple spray nozzle forthe purpose indicated, which is adjustable, making it possible byadjustment to throw a spray or a stream from the nozzle, as the operatormay desire, the adjustmentl being made wlthout discontinuing thespraying and without the necessity of the operator leaving hisaccustomed position.

A further important object is to provide for the quick and convenientclearing of the spraying aperture when same becomes clogged by forcingtherethrough a full stream of spraying liquid.

These objects, together with other objects apparent to those skilled inthe art, may be attained by the construct-ion illustrated in theaccompanying drawings, althouofh the invention may be embodied in otherForms, the construction illustrated being chosen by way of example.

n the drawings Figure 1 is a perspective view of a spray nozzleembodylng my invention mounted upon an extension tube. Fig. 2 is alongitudinal sectional view through a nozzle embodying my invention, theparts being shown in the spraying position. Fig. 3 is a similar viewshowing the arts, however, in the solid-stream position. ig. 4 is afront face view of the vortexhead. Fig. 5 is a longitudinal sectionalview of the parts comprising the nozzle separated from each other. Thesections shown in Figs. 2, 3 and 5 are taken on the line w-w shown onFig. 4, looking in the direction of the arrows there shown.

Throughout the several views-similar reference numerals indicate similarparts.

More specifically describing the construction disclosed in said drawingsthe numeral 1 indicates an inflexible extension tube, the lower end 2 ofwhich should be connected, as by a flexible hose, to a source ofspraying .liquid under pressure. Said tube is preferably made of metaland is of any length desired, from a few inches to many feet. On theupper end of said tube is mounted the spraying nozzle. The sprayingnozzle comprises a vortex thiinble provided with the hollow cylindricalbody 3 and the integral vortex head 4. Said vortex head is in the formof a disk having a greater diameter than the body 3, the outer edge 5 ofthe disk thus projecting beyond the cylindrical walls of the body 3 andforming the annular shoulder G. The end of the body 3 opposite the head4 is provided with internal screw threads 7 for attaching said body tothe tube 1, which should be provided at its upper end with correspondingexternal screw threads. The head 4 is provided with the inclinedvortex-producing apertures 8 arranged in the well known manner so as todirect vortex-producin streams into the nozzle cap. In the wal s of thebody 3 immediately back of the shoulder 6 are arranged a plurality ofradially disposed auxiliary apertures 9 for the purpose hereinafter tobe explained. Longitudinally slidably mounted upon the body 3 is the capretaining ring 10 provided at it-s forward end with an annular,externally screw threaded project-ion 11 of somewhat greater diameterthan the head 4. The back end of the retaining ring is preferablyexternally reduced and provided with the external screw threads 12adapted to receive the internal screw threads 13 of the packing ring 14which is provided with an inwardly disposed, annular packing-retainingflange 15 extending into close relation to the outer surface of the body3 and adapted to hold the packing 16 in position between the end of thering 10 and said flange, said packing being adapted to slidingly engagethe body 3, as will be apparent from an inspection of Figs. 2 and 3.

The nozzle cap is provided with the cylindrical side walls 17 providedinternally at the rear with screw threads 18 adapted to engage theexternal screw threads on the projection 11. The head 19 closes thefront end of the cap except for a small central spraying aperture 20,and the front face of the head 19 is preferably concave, in the mannercommon in the art. It should be noted that the length of the walls 17 issuch that when the cap is connected to the retaining ring 10, as shownin Fig. 2, and said retaining ring 10 engages the shoulder 6 there willbe sutlicient space between the head 4 and the head 19 to produce thenecessary whirl or vortex to cause a spray to issue from the aperture20. It should also be noted that the internal diameter of the cap isgreater than the diameter of the head 4 so that there is a space betweenthe outer edge 5 of the head and the inner sides of the walls 17.

The various parts, as described, having been assembled and connected tothe tube 1, when uid under pressure is forced through said tube into thenozzle the pressure of the fluid against the head 19 will cause the ring10 to slide forwardly on the body 3 until said ring engages the shoulder6. In such position, illustrated in Fig. 2, the auxiliary apertures 9will be closed b y reason of the ring 10 overlying the same, and theliquid being directed into the nozzle cap through the vortex-producinapertures 8 only will be caused to whirl within said cap and produce aspray issuing from the aperture 20. Should the aperture 20 becomeclogged and it be desired to clear the same, or should it be desired todirect a solid stream from the aperture 20, for any reason, as forreaching a distant point or applying an unusual quantity of sprayingliquid, the ring 10' together with the cap should be drawn back withrelation to the body 3, and against the force of the liquid in the capuntil the auxiliary apertures 9 are uncovered by the receding ring 10,as illustrated in Fig. 3. As soon as said apertures are uncovered liquidwill be directed through said apertures in radial directions against theside walls 17 and thence around the edge 5 of the head 4 into the frontportion of the cap, thus destroying the whirling action of the liquidwithin said cap, producing a solid head of liquid within said cap, andcausing a solid stream of liquid to be directed through the aperture 20.

It will be understood that in the practical use of the invention thenozzle is desired in the spraying adjustment the greater portion of thetime and that the throwing of a solid stream is desired onlyoccasionally. If it is desired to throw a solid stream onlyr for thepurpose of clearing the aperture 20 it may be most convenient to slidethe ring 10 back upon the body 3 by bringing the cap of the nozzle intoengagement with some object, as for instance the limb of a tree, andpushing forwardly upon the tube 1, or if the nozzle is connecteddirectly to the iexible hose for short-range work the ring 10 may bemoved back by the hand. In the spraying of trees and shrubbery, however,it will be understood that it is frequently necessary to use anextension tube of considerable length and it may also be more frequentlydesirable to direct a solid stream from the nozzle. For the purpose ofconveniently adjusting the nozzle from the lower end of the tube 1,therefore, a connecting wire 2l may be attached to the packing ring 14in any mechanical manner, said Wire extending along the tube 1 to apoint within convenient reach of the operator, where the lower end ofthe wire may be connected as at 22 to a bellcrank-shaped thumb leverhaving the spaced arms 23 pivotally connected to the two sides of thetube l, and a thumb lever portion 24 extending rearwardly. It will beapparent from an inspection of Fig. 1 that the operator by placing histhumb upon the lever 24 and pressing the same down into engagement withthe tube 1 will draw the connection at 22 rearwardly, thus pulling onthe wire 21 and bringing the nozzle into the solid-stream adjustmentshown in Fig. 3. l/Vhen the pressure upon the lever 24 is released theforce of the liquid within the nozzle cap will move the ring 10 andnozzle cap forwardly, thus automatically restoring the nozzle to thespraying adjustment.

It will thus be seen that, generally speaking, my invention may be saidto consist of a stationary member, comprising the body 3 with the head 4and a movable member, including the nozzle cap and the ring 10, thepacking ring 14 and packing 16 being a detail of relative unimportance,and that numerous-changes in the form and construction of the device maybe resorted to as circumstances may require or experience suggestwithout departing from the spirit of the inventionv or the scope of .theappended claims.
